What is X squared - Y squared divided by X-Y?
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
Two numbers have a product of 20 and a sum of 9 what are the numbers?
xy = 20 x+y=9 x=9-y y(9-y) = 20 9y-y(squared) = 20 0= y(squared)-9y+20 0= (y-5)(y-4) y= 5 or 4, x= 5 or 4 The two numbers are 5 and 4.
How would you write 3 times the sum of x and y squared plus 5 times the difference of 2x and y in verbal exprestion?
That verbal expression would read: 3(x+y)^2 + 5(2x -y) ^2 means 'squared' in the above example.
Y x squared 6 squared - 7?
-1
What is x squared plus y squared?
The sum of two squares cannot be factored. It can be represented thus: X2 + y2 = (x + yi)(x - yi) In this expression, the i is the symbol for the imaginary number the square root of -1.
What is the answer to 9 Times the sum of x squared and y decreased by 4 times the sum x squared and y?
5(x^2 + y)
What is the property used in verbal expression three times the sum of x squared and y squared?
distributive
What is X squared - Y squared divided by X-Y?
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
How do you factor x squared minus 2 x y plus y squared?
it is (x-y)(x-y) :)
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
When is x squared plus y squared equal to quantity X plus Y squared?
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
What is the square root of x squared plus y squared?
X + y
What does y x y eqeal?
Y squared (Y^2)
How do you factor x squared minus y squared?
The factoring is as follows: x2 - y2 = (x + y) * (x - y)
What is the GCF of x squared y and xy squared?
The GCF is xy
What is x squared plus 2xy plus y squared?
(x+y)2
